Therefore,detecting the surface defects of the finished ball is really important in the production of steel , for testing the surface quality of the ball,domestic enterprises and ball bearing manufacturers who almost used traditional methods of artificial visual ,in which way is easily affected by the level of detection technology workers, responsibility, fatigue degree of instability, and its high rate of false positives and missed, the low degree of the detection technology of surface quality of ball with foreign countries,there is a big gap made in China, causing one of the reasons for this disparity is that the detection technology of surface quality of ball the continuously requirements of improving the surface quality of the ball in bearing industry ,which bees very important is developing an affordable, high speed and efficiency, automatic detection device of surface quality of the ball. Ball surface defect detection based on optical fiber sensing technology research presented in this paper is based on the ball surface defects as the research object, the ball surface defect automatic detection technology, the purpose is to resolve the degree of automation of the ball surface quality detection low, low efficiency situation, developed with its own independent intellectual property rights of the ball appearance detector.Analyzing the workflow of the ball detection system, implementation of the ball deployment mechanism,analyzing the trajectory of expansion depends on latitude and longitude. Analyzed and designed signal processing system of ball surface defects based on modulation and lockin amplification technology ,which included the laser excitation drive circuit, the narrowband filter circuit, the phasesensitive detection circuit, the phase shifting circuit, the division circuit；C8051F020SCM is used for signal acquisition and processing，which included the power supply circuit,an external crystal oscillator circuit, reset circuit, serial munications, JTAG interface circuit, keyboard and display.Key words：Ball。System Design。根據(jù)統(tǒng)計(jì)數(shù)據(jù)可以知道：在各種各樣的球軸承的失效形式中，由于故障所造成的表面缺陷的鋼鐵高達(dá)80%。跟著鋼球行業(yè)制造工藝水平的不斷提高，在一定程度上，鋼球外貌缺陷的數(shù)目和品種有了較好的控制，但為了保證鋼球表面質(zhì)量不能全球企業(yè)只有提高加工工藝的
